Summary
Surgery for proliferative vitreoretinopathy (PVR) offers a 68% retinal re-attachment rate. While visual function improvement is limited, most patients would still opt for PVR surgery given the chance.
Area of Science:
- Ophthalmology
- Retinal Surgery
Background:
- Proliferative vitreoretinopathy (PVR) surgery can be lengthy with variable visual outcomes.
- Significant PVR membrane presence (≥3 clock-hours of grade C) poses surgical challenges.
Purpose of the Study:
- To evaluate the anatomical re-attachment rate and visual acuity improvement following PVR surgery.
- To assess patient satisfaction and perceived benefits of PVR surgery retrospectively.
Main Methods:
- Retrospective case note review of 47 consecutive patients undergoing PVR surgery.
- Included vitrectomy and membrane peel; follow-up averaged 9 months.
- Randomized telephone survey of 17 patients regarding surgical decision and outcomes.
Main Results:
- Retinal re-attachment achieved in 68% (32/47) of eyes.
- Mean visual acuity was 0.089 (approx. 6/72).
- Average of 2.15 PVR operations per eye; 65% would have the surgery again.
Conclusions:
- PVR surgery can achieve significant anatomical re-attachment.
- Patient-reported outcomes suggest a willingness to undergo surgery despite limited visual gains.
- Further research into optimizing visual function post-PVR surgery is warranted.
